Description

  The present disclosure relates to an assembly of a dispenser that delivers a flowable material. In particular, the present disclosure relates to an assembly for releasably securing a cartridge or foil containing a flowable material for use with a dispenser or dispense gun.

  Flowable materials such as adhesives or sealants are usually applied from containers. Known containers include cartridges and sausages or foils. The cartridge has a flowable material and a cylindrical rigid shell containing an outlet at one end and a piston at the other end. The cartridge is placed in a dispenser or dispense gun. Actuation of the dispenser causes the drive rod to move linearly to move the cartridge piston toward the cartridge outlet and push the flowable material out of the outlet. For larger applications, the flowable material is contained in a “sausage” or “foil”. Sausages and foils have a generally cylindrical container made of a flexible film type material. The flexible material is sealed around the flowable material and has an outlet at one end. The sausage or foil is placed in a dispenser or dispense gun. Actuation of the dispenser causes the plunger to move linearly at the end of the drive rod to collapse the sausage or foil and push the flowable material out of the outlet.

  Current dispense guns are not ergonomically placed, and installing or removing cartridges or sausages containing flowable materials, especially in a dispense gun with multiple cartridges, is a cumbersome and time consuming task . Some dispensing guns use a slot into which a cartridge nozzle is inserted. The slot allows the front of the cartridge to move up when the dispensing gun is activated and allows the dispense gun plunger to be off center. There is a need in the art for an improved assembly that allows easy and convenient installation and removal of cartridges for use with dispensers or dispense guns.

  The present disclosure provides an assembly for use with a dispenser or dispense gun. The assembly includes a front member that is rotatably movable and is movable between an open position and a closed position about the front plate. In the open position, the tubes in the assembly are accessible for loading or unloading cartridges containing flowable material. In the closed position, the cartridge is secured within the assembly. The assembly includes a rear plate that can be secured to a dispenser or dispense gun. The front plate and rear plate are secured together, thereby securing the tube within the assembly.

  In another aspect of the present disclosure, a combination of an assembly and a dispenser or dispense gun is provided.

  In another aspect of the present disclosure, a kit is provided that includes an assembly, a dispenser or dispense gun, and a cartridge or foil that includes a flowable material.

  These and other features and advantages of the present disclosure will become apparent from the following detailed description of exemplary embodiments of the present disclosure read in conjunction with the accompanying drawings.

The opening 24 may include a releasable seal (not shown) and / or an outlet (not shown) for fluidly connecting the mixing manifold, mixing nozzle or dispensing nozzle to the cartridge 14. The dispenser 12 has a piston or plunger 40 that is movable in a longitudinal direction between a position adjacent to the rear plate and a position toward the front plate by the operation of the dispenser. Movement of the piston or plunger 40 toward the front plate can push the flowable material 20 out of the sausage or foil 26. As the flowable material is dispensed, the flexible foil or bag 30 collapses. Other techniques for extruding the flowable material 20 from the container 24 can be suitably used.

  The flowable material 20 may be a viscous or pasty flowable material. Useful materials include, but are not limited to, caulking agents, sealants, adhesives, and the like. The flowable material 20 used in the combination 10 may be the same or different in the containers 14, 30. The flowable material 20 can include multi-component systems that react chemically upon mixing, such as, but not limited to, 2 parts epoxy and 2 parts polyurethane. In the case of such a multi-component material, one component may be disposed in one of the containers 14, 30 and a different component may be disposed in the other of the containers 14, 30. In other forms, the tubes 102, 104 are replaced with a single dual-shaped container (not shown) having two open lumens in the configuration of FIG. 8 where different components are placed in different lumens. . In such a case, the container can have a geometry (not shown) that matches the configuration of FIG. 8, such as two parallel sausages joined by a web of material. In other forms, the flowable material 20 may be a one-component material such as, for example, a one-component polyurethane composition that crosslinks and cures when exposed to moisture. In this form, one or both of the tubes 102, 104 include a cartridge or foil that includes the same material.

  FIG. 4 is a front view of the release assembly 112 of FIG. The first movable member 114 has an upper portion 122 and a lower portion 120, and the second movable member 116 has an upper portion 126 and a lower portion 124. The respective upper portions 122, 126 of the first and second movable members 114, 116 are rotatably engaged with a hinge portion or hinge mechanism 118. Accordingly, the upper portions 122 and 126 of the first and second movable members 114 and 116 can move from the closed position shown in FIG. 1 to the open position shown in FIG. 4. In the open position of the first and second movable members 114 and 116, the tubes 102 and 104 having the containers 14 and 30 are exposed. The containers 14, 30 may be removed from the tubes 102, 104 and then new containers 14, 30 may be placed in the tubes 102, 104. Next, the first and second members 114 and 116 are moved to the closed position as shown in FIG.

  As shown in FIG. 4, the first and second members 114, 116 are movable around the front plate 108. The first and second members 114, 116 can include manifold spacers 128, 130, respectively.

  The upper portions 122, 126 of the first and second movable members 114, 116, respectively, may have holes or apertures 132, 134. Wear bushings 136, 138 may be fixedly disposed in the holes or apertures 132, 134. The wear bushings 136, 138 are useful for the locking mechanism 119 described in more detail below. Bolts 142 and 144 are useful for securing tie rod 110 to front plate 108.

  FIG. 5 is a partial perspective and rear view of the release assembly 112. Lock plate stop protrusions 150 and 152 may be disposed on the bottom 153 of the front plate 108. The lock plate stop projections 150, 152 can be used to limit the degree of rotation of the respective lower portions 120, 124 of the first and second members 114, 116 around the hinge mechanism 118.

  The front plate has openings 146, 148. The tubes 102, 1044 may be fixedly disposed within the respective orifices 146, 148. For example, the tubes 102, 104 may be threadably threaded into the orifices 146, 148. However, the present disclosure is not limited to this, and other techniques for fixing the tubes 102 and 104 to the front plate 108 can be suitably used. For example, the tubes 102 and 104 are press-fitted into the orifices 146 and 148, the tubes 102 and 104 are welded to the orifices 146 and 148, the tubes 102 and 104 are bonded to the orifices 146 and 148 by bonding, or the front plate 108 and the tubes 102 and 104 may be formed as a unitary structure.

  The upper portion 117 of the front plate 108 includes a lock mechanism 119. The lock mechanism 119 may be in the form of a spring loaded lock pin 140. An example of a useful spring loaded lock pin 140 is shown in FIG. The spring loaded lock pin 140 can include a slidable portion 154, a threaded portion 156 and an access portion 158. The screw portion 156 can be screwed into the front plate 108. The spring-loaded lock pin 140 is normally biased so that the slidable portion 154 4 extends from the threaded portion 156 as shown in the upper view of FIG. In this configuration, as shown in FIG. 1, when the first and second members 112 and 116 are in the closed position, when the threaded portion engages with the front plate 108, the slidable portion 154 Each member 114, 116 is disposed within a respective wear bushing 136, 138. This represents the locked position of the spring loaded lock pin 140.

  The access portion 158 can be pulled or otherwise manipulated to pull the slidable portion 154 back to the screw portion 156 against the biasing force, as shown in the lower view of FIG. This represents the unlocked position of the spring loaded lock pin 140. The access portion 158 can rotate to temporarily lock the spring loaded lock pin 140 in the unlocked position. In the unlocked position, the first and second members 114, 116 can rotate and hinge in their open positions, as shown in FIG. Due to the rotation of the access portion 158 from the unlocked position, the slidable portion 154 can automatically extend under the biasing force. In this embodiment, the user can retract the access part 158 to pull out the slidable part 154, rotate the access part 158, and fix the slidable part 154 in the pulling position with one hand. When the slidable portion 154 is pulled out, the first and second members 114 and 116 are automatically opened under their biasing force. After the container is inserted, the user closes the first and second members 114, 116 rotatably with their one hand against their spring bias and rotates the access portion 158 to automatically slide the slidable portion 154. And the first and second members 114, 116 can be locked in the closed position. However, the present disclosure is not limited to using spring loaded lock pins 140 and other suitable locking mechanisms can be used appropriately. Access portion 158 may be located on top 117 of front plate 108 and may provide a position for detent 115 to hold the spring loaded lock pin in the locked position.

The movable member upper portion 126 has a substantially triangular protrusion 74 including an inclined surface 75 and a shoulder portion 76. Referring again to FIGS. 30a and 30b, the front plate upper portion 117 includes a protrusion (not shown) to which a locking mechanism 78 is movably attached. The locking mechanism includes a release portion 80 attached to the protrusion by a pin 82, the release portion being a release position away from the upper portion 122, 126 from a locked position (shown in FIG. 30a) adjacent to the movable member upper portion 122, 126. (Shown in FIG. 30b) so that it can be rotated around the pin by the user. The locking mechanism preferably includes a biasing element such as a spring that resiliently biases the release portion 80 to the locked position. The release portion includes an opening engageable with the protrusions 70 and 74. The user can push the rear of the release portion down toward the tube 102 and raise the release opening 84 away from the projections 70, 74. Thereby, the movable members 114 and 116 can be moved to the open position shown in FIG. In the open position, the user can remove or insert the container 14 or 30 from the tubes 102, 104. When the user releases the rear part, the release part 80 is biased toward the locked position. The user can move the movable members 114 and 116 to the closed position. As the projections 70, 74 approach the release portion 80, the ramps 71, 75 allow the lugs 70, 74 to move within the release opening against biasing the release portion 80 against the biasing force. When the protrusions 70 and 74 are in the release opening, the release part 80 is biased toward the closed position, and the shoulders 72 and 76 of the protrusions abut against the release opening to move the movable members 114 and 116 to the closed position. maintain.
